To "finger the bass" means to finger a vagina with skill. Bass guitarists are known to have skilled fingers, and fast hands, and often "finger" the notes to produce the sounds on their instrument. This is also a pun on the word "bass" and "bass", "bass" being short for a bass guitar, and "bass" being a type of fish. Vaginas are often referred to as being "fishy". Haha, great pun, I know!
"So, since you're a skilled bass guitarist, does that mean you'll be good at 'fingering the bass', as it were?"
Fucking stupid of all Meghan Trainor songs. And all of her songs are stupid. This song is tired, out dated, and annoying. Also this phrase is used to describe fatness
Radio: Because you know I'm all about that bass Everyone: Ya we know you're fat
